There are no approved therapies for the treatment of sarcoidosis. Corticosteroid (steroid hormone) therapy is considered the standard treatment. Only limited benefit has been shown when using corticosteroid therapy to ease lung symptoms or improve lung function in patients with sarcoidosis. Also, the effects of other therapies (for example: methotrexate, cyclophosphamide, anti-malarial drugs, thalidomide) and other immunosuppressants (drugs that suppress a body's natural defense system [immune system]) which have been used in a small number of patients are not well known and can cause long term problems.
